One mystery is the relative rarity of V-type (Vestoid) or basaltic asteroids in the asteroid belt. [79] Theories of asteroid formation predict that objects the size of Vesta or larger should form crusts and mantles, which would be composed mainly of basaltic rock, resulting in more than half of all asteroids being composed either of basalt or ...
The asteroid and comet belts orbit the Sun from the inner rocky planets into outer parts of the Solar System, interstellar space. [ 16 ] [ 17 ] [ 18 ] An astronomical unit , or AU, is the distance from Earth to the Sun, which is approximately 150 billion meters (93 million miles). [ 19 ]
Observations of the asteroid belt, located between Mars and Jupiter, suggest that the water snow line during formation of the Solar System was located within this region. The outer asteroids are icy C-class objects (e.g. Abe et al. 2000; Morbidelli et al. 2000) whereas the inner asteroid belt is largely devoid of water.
A small asteroid will be pulled into orbit around the Earth as a “mini-moon” later this month before the space rock departs into other parts of the solar system.. The 10m-wide asteroid, dubbed ...

10 Hygiea is a major asteroid located in the main asteroid belt.With a mean diameter of between 425 and 440 km and a mass estimated to be 3% of the total mass of the belt, [11] it is the fourth-largest asteroid in the Solar System by both volume and mass, and is the largest of the C-type asteroids (dark asteroids with a carbonaceous surface) in classifications that use G type for 1 Ceres.
Sample of asteroid Bennu will help tell us where we came from, scientists hope Pieces of distant, ancient asteroid arrive on Earth from Nasa spacecraft, after travelling billions of miles Skip to ...
Asteroid groups out to the orbit of Jupiter, showing eccentricity versus semi-major axis. Hungaria asteroids are the left-most dense grouping in blue. The core region of the asteroid belt is shown in red. Same as above, but showing inclination versus semi-major axis. Hungaria asteroids are the (top-)left-most dense grouping in blue.
